Sampler

Sound Generator

The Sampler is an object that plays back different types of sample based instruments. A note is triggered as soon as the object is put on the table. Rotating the object also triggers a note. The Sampler is either used together with a sequencer, played via MIDI input or standalone with the Tonalizer object. The Sampler object supports the Soundfont (SF2) format and the Reactable Instrument format (RIN).


Pitch

When rotating the object a note is triggered. The outer half circle on the left side shows which half-note is played back. The inner circle shows the octave the sampler is currently in.

Amplitude

The maximum amplitude of the sampler can be changed by moving the dot on the right side of the object. The position of the dot can be locked and unlocked by dragging it away from the object until it turns red.


Subtypes

Instrument Mode

In instrument mode, the notes played depend on the base note of the Sampler (which is controlled through rotation) and the note from the sequencer. Therefore it is possible to pitch shift a sequence by rotating the Sampler object.

Drum Mode

In drum mode the notes which are triggered by the sequencer are always absolute and can not be changed by rotating the Sampler.

RIN Mode

The RIN sample format is a Reactable intern sampler format which lets the user assign sounds to notes. Each note can only have one sound. If a note does not have a sound assigned it uses the sound of the note which is closest and pitches it according to the distance. This can be used to create drumsets and melodic instruments alike.

RIN instruments can be loaded with the instrument browser and are xml files which are stored in the Instruments folder. When creating a patch and storing it the corresponding instrument files are automatically created in the Instruments folder. The samples used are stored separately in the Samples folder.

Panels

Instrument Browser

The instrument browser allows to change the instrument setting. More info

Sound Browser

The Sound Browser is active for the RIN mode and assigns sample sounds to the currently selected note. On the Sampler the notes with assigned samples can be distinguished through the thicker bar. More info

Keyboard Panel

The Keyboard Panel can be used to play single notes. It is similar to a piano keyboard but has an abstract layout which adapts to the currently set scale. The base note of the sample is on the left and the keyboard covers 2 octaves starting and ending with "C" (the tonica)". By turning the Sample object the octaves can be selected.

In RIN mode the keyboard also shows the notes with samples by highlighting the corresponding keys.
